eating my kowhai
camouflaged caterpillars are eating all the leaves off young kowhai
trees. Should these be removed if possible? I have some vague memory
of hearing something good about these caterpillars!
caterpillars of a number of different moth species will eat the
leaves of kowhai trees. Some of these are native, some are not,
but it is most likely to be the native kowhai moth. Usually this
does not completely defoliate a tree, and as long as the tree is
otherwise healthy, you can safely leave the caterpillars alone and
the tree will recover.
However, if the tree
is heavily infested, you may wish to try an insecticide spray. If
you live in or near west Auckland, you would be wise to contact
MAF, as kowhai is a host species of the painted apple moth.
